Pads

Hi again,

Sorry for the newbie question but I'm really at my wit's end.

I would like to change the diameter of the pads to the passive components on

the already routed board image but the CHANGE command won't let me, even if

the Pads layer is active. All I get is a rude noise, even while the status

bar tells me to left-click on the component I want to change.

Also, it would make my life a lot easier if I could duplicate a section of

the board elsewhere on the same board without having to do it in the

schematic editor. Imagine 2 channels of a stereo system placed side by side

with interconnecting circuitry routed manually. This would look neater, not

to mention making trouble-shooting a lot easier on the actual physical

hardware.

Any help would be gratefully appreciated.

Thanks,

Martin

 

 

 

Yeah, that got me too when I first started with Eagle. To change the

pads, you have to open the library and edit the package for that part in

the library.

1. To figure out what library the part is in, click Info (the i button)

and then click the part. It will tell you the Library name and the

package name in that library.

2. Find the Library in the Control Panel under Libraries, then

double-click the library name (not a component or the package) to open

the Library.

3. Now click Library->Package from the Library's menubar. Select the

package name you got from step 1. Now use Change->Drill or

Change->Diameter or Change->Shape on the pads.

4. Once done, save the library, and go back to the board window. Now

click Library on the board's menubar, and then click update all. Viola!

I recommend you start creating your own libraries of updated parts. This

will prevent you from overwriting your changes when you update eagle.

Once you have created a new lib file, you can open the lib and then copy

parts from eagle's lib to the open one, which simplifies the whole process.

As for the 2nd part: you can, but it's not intuitive. First, finish with

your schematic and board. THen copy the board file, and open the copied

file in eagle. Now do a group and cut and paste to copy the entire

layout to another section of the board. Now manually run needed tracks

between the two.
